Variation Or Replacement Of Contract?

The Supreme Court has provided guidance on what might constitute a variation of a contract, as opposed to the replacement of one, albeit in a judgment that ultimately didn't require an answer to that question.

Introduction

In a judgment handed down in late 2024 in R (on the application of Cobalt Data Centre 2 LLP and another) v HMRC [2024] UKSC 40, the Supreme Court ultimately dismissed the appellant taxpayers' appeal against HMRC's decision to reject allowances under the Capital Allowances Act 2001 ("CAA 2001") in connection with an enterprise zone scheme.

Whilst the case arose in a tax context it provides useful guidance as to contractual alterations (to use a neutral term) more broadly and may well have wider application going forward.
